“…Rave & Baldassarre (1989) had also reported high preening in October and November while working on activity budget of the Green-Winged Teal wintering in the coastal wetlands of Louisiana. In waterfowl, as in many birds species, females prefer brightly adorned males (Andersson 1994), perhaps because males with the brightest plumages are in the best condition (Hill & Montgomerie 1994).…”

Diurnal activity budgets of the Large Whistling Teal Dendrocygna bicolor were quantified in Deepor Beel wetlands from March 2007 to January 2008. The study revealed that the Large Whistling Teal utilized 36.1% of time in resting, 37.1% in locomotion, 21.8% of diurnal time in feeding and 3.9% of diurnal time for preening activity. The teal spent <1% time in each, of alert and aggressive behaviours.

“…The activity budgeting studies quantify the time allocation of animals in behavioural activities (Rave & Baldassarre 1989). The activity budgeting studies of any waterfowl and other migratory birds can provide an insight into the role of the seasonal use of habitats in relation to the annual cycles of birds.…”

“…The time-activity budget has been recognised as an important tool for understanding habitat use and niche separation (Rave and Baldassarre, 1989), and consequently it is an invaluable aid for managing waterfowl communities and habitats. Fieldwork was carried out between the months of November and March each winter from 2007-2008 to 2008-2009 in Garaet Hadj Tahar (site A) and during 1 wintering season (from November 2007 to March 2008 only, because it underwent a dry period until December) in Garaet Timerganine, and consisted of behavioural monitoring.…”

“…Focal-animal sampling involves observing an individualnormally chosen at random -for a known period of time (Altmann, 1974). Behaviour is usually recorded at pre-determined time points (Miller, 1976;Asplund, 1981;Tome, 1991;Rave & Baldassarre, 1989;Zicus & Hennes, 1993;Petrie & Rogers, 1997;Petrie & Petrie, 1998), although another approach has been to record to length of time the focal individual is engaged in a particular behaviour (e.g. Bergen et al, 1989I Józkowicz & Górska-Klek, 1996.…”

SummaryScan sampling is a common technique used to quantify the activities of animals, including waterfowl. When large numbers are present, it is often impractical to record the activities of each individual, and sub-sampling is employed. We present a method for the design and analysis of scan sampling studies involving sub-sampling, based on an actual study of waterfowl activity on a waste stabilisation pond. The design we propose avoids subjectivity in the selection of individuals,is truly random rather than haphazard, and is adaptable to other situations. It allows for the population on each sampling occasion to be divided into separate strata with samples taken from each. The method of analysis addresses the statistical issues arising from such designs. In estimating the proportion of individuals engaged in an activity, it uses the information from observations in which some of the individuals are counted but their activities not recorded, and estimates the sampling variance introduced by sub-sampling. In comparing the mean proportions for different levels of a factor, such as time of day, the method uses restricted maximum likelihood (REML), an algorithm which can account for the sampling variance as well as for missing data. It is anticipated that the methods described
